Coherent has expanded the wavelength tuning range of its Legend tunable ultrafast amplifier into the blue and ultraviolet spectral regions
Specifically, the company has introduced two new standalone modules: a second harmonic (SHG) module that provides frequency-doubled output from 375nm to 450nm; and a third harmonic (THG) module that delivers frequency-tripled output from 250nm to 300nm.
These modules, when combined with the tunable fundamental output of the Legend (750 nm to 900 nm), can perform many cost-effective, wavelength-sensitive ultrafast applications without the use of an optical parametric amplifier.
Legend is the new product name of the high-energy, Ti:Sapphire regenerative amplifiers first pioneered by Positive Light over ten years ago.
When pumped by a Coherent Evolution laser, these unique Legend amplifiers provide femtosecond and/or picosecond pulses with pulse energies up to 2.5mJ, repetition rates up to 5kHz, and unmatched pulse-to-pulse stability.
The addition of the SHG and THG modules makes the Legend an ideal source of tunable, high-energy ultrafast pulses for applications such as pump-probe experiments to study molecular dynamics, photochemistry, photo-electron generation at optimized wavelengths, fluorescence upconversion, and research into non-linear optics.
